BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying tank for a grain dryer, which facilitates smooth flow of contained grains during grain drying and facilitates assembly at the time of assembling the drying tank.

[0002]

In the grain dryer for drying the grains stored in the upper drying tank while letting them flow down into the ventilation drying chamber in the lower part, the grain flow guide installed inside the drying tank is used. The work of assembling the inclined plate is troublesome and time-consuming. The present invention makes it possible for one person to easily assemble the inclined plate.

[0003]

According to the present invention, the front and rear side walls 5 and the left and right side walls 6 are provided at the four corners 4 of the drying tank 3 having the inclined plate 2 for guiding the stored grains down to the ventilation drying chamber 1 below. The obtuse angled side wall 7 is integrally formed with the front and rear side walls 5,
The front and rear ends 8 of the inclined plate 2 can be supported by the corner-cut side walls 7 and the drying tank of the grain dryer is configured.

[0004]

When the drying tank 3 is assembled, the inclined plate 2 is inserted between the front and rear side walls 5 so that when the inclined plate 2 inclines outward, the front and rear end portions 8 are integrated with the front and rear side walls 5. It is supported by the cut sidewall 7 and is prevented from falling outward and falling. With the inclined plate 2 supported in this manner, the front and rear end portions 8 are
Can be connected and fixed to the front and rear walls 5 to the corner cut side walls 7 by bolting or the like. Therefore, when assembling the inclined plate 2, a simple and easy assembling work can be performed by one person without requiring a special supporting structure or operation.

Since the corner cutting side walls 7 are formed at the four corners 4 of the drying tank 3 and are formed at an obtuse angle with respect to the front and rear side walls 5 and the left and right side walls 6, the resistance force when the stored grain flows down. Is made smaller to allow smooth flow-down.
Since it is assembled as an integral structure with the front and rear side walls 5, the structure is simple.

EXAMPLE A grain dryer is a circulating hot air drying mode in which hot air is blown in a ventilation drying chamber 1 for drying while circulating and transporting grains. The drying tank 3 is arranged in the upper part to accommodate the grains supplied by the grain elevator 9, and in the lower part, the mountain-shaped sloping plate 10 in the central portion and the sloping plates 2 on both left and right sides of the front and rear side walls 5 are arranged. Are arranged to allow the grains to flow down to the ventilation drying chamber 1 below.
The drying tank 3 is assembled from an upper tank 11 and a lower tank 12 having the inclined plates 2 and 10.

In the lower base frame 13 on which the drying tank 3 is mounted, the ventilation drying chambers 1 having the drying nets 14 on the left and right sides are arranged in two rows, and a burner 15 is provided between the left and right ventilation drying chambers 1. A hot air chamber 16 for sending hot air is formed, and an air exhaust chamber 17 for guiding exhaust air ventilated by each ventilation drying chamber 1 is formed outside each ventilation drying chamber 1. Reference numeral 18 denotes an outer wall on the outside of each exhaust chamber 17, and 19 denotes a bottom gutter plate. A lower part of the gutter plate 19 is provided with a transfer spiral 20 extending in the front-rear direction. The dried grain fed by rotation is received and transferred, and is sent from the terminal end to the grain fried machine 9 to be transported by fried grain.

The drying tank 3 is formed into a rectangular box shape by the front and rear side walls 5, the left and right side walls 6 and the corner cut side walls 7 of the four corners 4, and the joints of these side walls 5, 6 and 7 are located outside. It is an assembling form that has a matching rib 22 and can be tightened and fixed by a bolt 23. Of these, the corner-cut side walls 7 are attached to both left and right ends of the front and rear side walls 5, but may be integrally formed by a single plate.

A mountain-shaped inclined plate 1 arranged in the lower tank 12.

At this time, the front and rear end portions 8 of the inclined plate 2 are supported by the corner cut side wall portion 7 which is integrated with the front and rear side wall portions 5. In this state, the overlapping portions of the mating ribs 24 formed on the front and rear end portions 8 of the inclined plate 2 and the front and rear side walls 5 and the corner cut side walls 7 are fixed with bolts 25.

When the assembling of the inclined plates 2 and 10 is completed in this way, the outer left and right side walls 6 are assembled between the front and rear side walls 5. When the lower tank 12 is assembled, the upper tank 11 is assembled. The outer wall 18 of the base frame 13 is configured to be pivotable outward so that it can be projected outward from the top of the gutter plate 19, and the grain from the open opening of the outer wall 18 to the transfer spiral 20. It is configured to be able to supply. A burner 15 is communicated with the front side wall of the hot air chamber 16, but an exhaust chamber 17 is provided on the side of the burner 15.
A suction / exhaust fan communicating with the transfer spiral 2 is provided.
A grain elevator 9 that communicates with the 0 gutter 26 is arranged.

The grains contained in the drying tank 3 flow down in the ventilation drying chamber 1 by the rotation of the feeding blades 21. Here, the hot air flowing from the hot air chamber 16 to the air exhaust chamber 17 is received and dried. The grains fed by the feeding blades 21 are transferred through the transfer spiral 20 gutter 26, and returned to the drying tank 3 through the grain lifting machine. This upper tank 1
Grains that flow down from the inside of the lower tank 12 from inside 1 are guided by the corner cutting side walls 7 at the four corners 4, so that the grains flow down smoothly, and uneven drying of the grains hardly occurs. Lower tank 12
Then, it is guided by the mountain-shaped inclined plate 10 and the inclined plate 2 on the outer side, and is guided into the ventilation drying chamber 1 having a narrow width.

6 to 9 are different from the above example in that
With respect to the structure of the shelf plate 27 provided below the hot air chamber 16, the mounting structure of the shelf plate 27 is simplified and cleaning of the shelf plate 27 is facilitated. On the rear side of the base frame 13, there is provided an air exhaust box 29 which communicates between the left and right air exhaust chambers 17 and the suction air exhausters 28, and the shutter 31 of the shelf board 27 is provided on the rear wall 30 on the lower side. A shutter opening 32 that can be inserted is provided, and the lid 45 can be closed from the outside.

The shelf plate 27 has the feeding blades 2 at both left and right ends.

It is formed. Under the shelf plate 27, there is a rail 37 that receives the left and right side portions of the shutter 31 slidably back and forth, and the scrapers 35, 36 approach the upper side surface of the shutter 31 guided by the rail 37. .

Further, a front-rear direction operation rod 38 is provided below the shutter 31. The hook 39 at the rear end of the operation rod 38 can be engaged with the locking portion 40 at the rear end of the shutter 31, and by engaging the hook 39 with the locking portion 40, the handle 41 at the front end portion is moved to the front side wall. The shutter 31 can be pulled out forward from 42 and the shutter 31 can be moved in the front-rear direction A so that the scrapers 35 and 36 can clean the accumulated dust.

When cleaning the accumulated dust on the upper surface of the shelf board 27, the burner 15 case 43 of the front side wall 42 is rotated forward to open the front opening 44 of the hot air chamber 16, and the front opening 44 is opened. Insert a cleaning tool such as a scraper to clean.
10 and 11, the point different from the above example is that the controller that performs the drying operation of the grain dryer is set to a state in which ventilation drying is performed by turning on the power (ventilation drying mode), and the grain is changed. By setting the swelling amount and turning on the drying switch, the ventilation operation is automatically performed.

The control box 46 has a feed switch 47 for feeding grains into the drying tank 3 and the burner 1
5 and the suction / exhaust fan 28, a drying switch 48 for driving each part of the feeding blade 21 to start drying, a discharge switch 49 for taking out dried grains to the outside of the machine, a stop switch 50 for stopping the drying work, and the like are arranged. Also, below these switches,
Drying setting switch 51 for setting the drying speed according to the type of dried grain, its setting display lamp 52, moisture setting switch 53 for setting the set moisture value of the drying target, its setting display lamp 54, and a drying tank A stake amount setting switch 55 for setting the swell amount of the grain with respect to No. 3 and its setting display lamp 56 are arranged.

Each time these setting switches 51, 53, 55, etc. are pressed once, LED display lamps 52, 5 for setting display are displayed.
4, 56 move sequentially from the left side to the right side, and when passing the right end, move to the left end. Also, the stake amount display lamp 5
In FIG. 6, there is a ventilation drying lamp 57 at the right end, which indicates that ventilation drying is performed in which outside air is blown into the ventilation drying chamber 1 for drying (ventilation drying mode).

This ventilation drying lamp 57 is turned over by turning on the power switch, and the drying switch 4
When 8 is turned on, ventilation drying is started. It should be noted that, when the grain is stretched in the drying tank 3, the ventilation switch 47 may be turned on to start the ventilation drying. Also, after setting the amount of stake, the stake switch 47 is turned on, the drying switch 48 is turned on, the discharge switch 49 is turned on, or the stop switch 50 is turned on.
Alternatively, the ventilation drying may be started.

[0021] However, as a form of the drying operation, a ventilation drying operation is often carried out after the grain is put in, and then a hot air drying is often carried out, so that a safe drying can be carried out.
